To all whom it may concern:

Be it known that I, ENRIQUE SANCI-IIS, of Rue Pierre Charron, in thecity of Paris, Republic of France, engineer, have invented Improvementsin the Frames ofAutomobiles, of which the following is a full, clear,and exact description.

The present invention has for its object a system of motor car withthree or four wheels essentially characterized by the special c011-struction of its frame and its method of suspension. These arrangementspermit of doing away with the ordinary construction of car-body whilegiving to the driversseat the form of seats used for large carriages, ofsuspending this seat comfortably and of bringing to the convenience ofthe driver all the mechanism of the control and steering gears, whichcan be arranged in the same manner as in a large vehicle and withoutdiminishing the simplicity of construction of the tri-car, while givingit a definite solidity. The invention is essentially characterized by:1st the constitution of the principal chassis forming the, properlycalled chassis and the body of the car. This chassis is applied directlyor by the intermediation of springs upon the forward axle and the backwheel and is formed by two bars so shaped as to form the body of the carbraced in the middle; 2nd by the application of a second chassis made oftwo parts at different levels. That lower part toward the front formsthe floor of the vehicle, the other part to the rear forms a seat forthe driver; this second chassis rests upon the first directly or by theintermediation of springs which are placed on the one hand under thefloor and on the other hand on the underside of the seat, thereby givingto the second chassis a great elasticity and a perfect stability.

By way-of example, this invention is represented in the drawings annexedin which.

Figure 1 is an elevation of a tri-car constructed according to thepresent invention. Fig. 2 is a plan view. Fig. 3 is a front view. Figs.4 and 5 show respectively a longitudinal and a cross section. Figs. 6and 7 are an elevation and a front view of a modification. Figs. 8 to 12show other modifications.

With reference to Figs. 1 to 5 of the drawing it will be seen that thefirst chassis is constituted by the two side frames a of which the lowerpart is curved as shown in Fig. 1 and of which the central portion isstrengthened so as to give to this frame the required rigidity andraised so as to form the car-body.

Fig. 2 shows the form which these frames present in plan arranged so asto be carried upon the extremities of the forward axle b and upon theaxle 0 of the back wheel. In the case of a four wheeled car the two sideframes are straight and parallel. These two frames a are connectedtogether at their upper part by the plate 01 in the form of a trapeziumapertured or not or by cross-bars in such a manner that the whole willform an absolutely rigid structure.

The second chassis presents a front part c forming the platform of thevehicle, and an after part f raised to the level of the seat andconnected with the first one for example by a cross-stayf the secondchassis carries the motor g the steering and the control gear and theseat g of the driver. It rests upon the first chassis through theintermediation of two sorts of springs; at the front it rests upon twolaminated springs h i, the second set of springs being hinged to theextremities of the axle 1). Of the other part, the rear of the upperchassis is supported upon the under chassis by means of a spring j. Inthe drawing is shown a single spring but it is evident that similarsprings can be placed laterally or they may be springs of quite anotherform. In order to secure a better mounting of the movable chassis, thecross-stay f is suspended by means of a ring f 2 from the end of thelower branch of spring j.

To prevent a too great fiexure of the spring the principal chassis a isprovided with blocks Zr: of elastic material, for example of rubberadapted to limit the downward motion of the seat. The tri-car thusconstituted can be furnished with a protective cover for the motor, orwith movable panels forming a covering box.

The power transmission may be made to the motor wheel either by chain orpinion gear. In this disposition as in the following the motor can beplaced upon one or the other of the chassises.

In case the cooling of the motor is effected by a circulation of water,the radiating tubes can be arranged as shown in Figs. 4 and 5 on thesides of the principal frame, the two side frames a of the latter beingeach provided with an opening a for the passage of air; radiating tubescan also be arranged on the rear side and even on the four sides.

ICC

The motor can be inclosed within a cover box or specially arrangedprovided with an outlet opening n arranged at the rear and of smallersection than the inlet opening 11 arranged at the front. Under theseconditions, the speed at which the air comes out is accelerated and ofcourse a greater cooling of the motor results therefrom.

In case of the use of radiators arranged as above specified against therecessed parts a of the chassis, the cover box it would be closed at itsrear part, so as to cause the air entering through the front opening tocirculate around the motor, this air being allowed to escape through thelateral openings at only after it has impinged against the radiatingtubes.

In order to avoid any introduction of small stones and dust into thecover box n, the inlet opening 12 will be provided with a wire gauze.

Figs. 6 and 7 show a modification of the preceding type in which thepart c of the upper chassis is prolonged toward the rear so as to permitof carrying the motor, the change speed gear, and other mechanism, moreeasily. The suspension of the rear is made as in the precedingarrangement; the suspension of the front is a little different and iseffected by two springs h 'L connected in the middle by a ring Z ofelastic material such as india-rubber, which is designed to form adeadener. The upper chassis has been in this arrangement provided wlthtwo seating places.

Fig. 8 shows a further modification in which the under chassis is fixedelastically to the axles. For this purpose the extremities of the sideframes are terminated by laminated springs m which are connected to theaxle. This figure represents a car with four wheels provided with twochassises mounted exactly as has been above described, and thisarrangement is equally applicable to tri-cars. As the under frame inthis case is suspended, it is possible in this arrangement to avoid theuse of the interposed springs between the two chassises. These examplesshow that the system of chassises and of suspension applies equally totri-cars as to four wheeled cars and permits in one or the other, thatthe lower chassis may be fixed rigidly to the axle-trees, or may beconnected elastically to these axietrees, the two chassises beingconnected rigidly or elastically to one another,

the vehicle having thus either a simple mode of suspension or equally adouble mode of suspension. Of course, the principal chassis can bemounted on the axle-trees by any other method of elastic suspension forinstance through straight springs m as shown in Fig. 9.

Fig. 10 shows another modification characterized by the fact that themotor-car comprises a rear seat p resting on the one hand on theside-frames a of the principal chassis and on the other hand on the rearaxle-tree. These arrangements, besides the advantages described hereinabove enable one to arrange upon the vehicles more particularly upon thetri-cars, a carriage body similar to those of large motor-cars,presenting the following advantages z-The lower frame is provided withgreat stability and is easy to construct, as for example in sheet ironof channel section, or in forged steel or may be in cast parts of onlythree pieces.

The control and steering mechanism can be placed in the ordinary way orunder the seat where the space is free.

The side frames a can be of variable shapes according to the severalapplications and can be limited at their lower part either by straightlines, curved lines or any combinations of straight and curved lines.

In cars with four seats, the two side frames (1 of the principal chassiscan each be formed with two higher parts, as shown in Fig. 12, whichform the bodies of the two seats.

Fig. 12 shows in longitudinal section another modification in which theraised parts of the two side frames a are provided with extensions aadapted to form the two sides of the seat, the seat properly called fand its back are then secured to these extensions (1 of the side framesa; in this case, the carcass of the car is simply composed of threeparts, the two side-frames a and the seat the two side frames a will bemounted upon the axle-trees by means of an elastic suspension.

The arrangements described are given by way of example the forms,dimensions and arrangements of detail might be varied considerablyaccording to circumstances without modifying the principle of invention.
